CNX Software ☛ Datanoise PicoADK v2 music synthesizer is a Raspberry Pi RP2350 board for audio experimentation
After the success of PicoADK v1, Datanoise has recently announced the launch of its PicoADK v2 music synthesizer built around the Raspberry Pi RP2350 MCU. The board supports projects like custom synthesizers, audio effects, and noise generation, and the 8 MB QSPI PSRAM of the RP2350 makes it ideal for memory-intensive applications such as long delays. Additionally, it features a SWD debug port, microSD card support, a MIDI-in circuit with an optocoupler, USB Type-C, user and power LEDs, and more. Previously, we have written about various similar synthesizer boards, like the Arduino-based MIDI controller, and we have seen products like the TinyLlama x86 retro computer, which uses the Raspberry Pi Zero 2 W as a MIDI synthesizer.

CNX Software ☛ OpenUC2 10x is an ESP32-S3 portable microscope with AI-powered real-time image analysis
Seeed Studio has recently launched the OpenUC2 10x Hey Hi (AI) portable microscope built around the XIAO ESP32-S3 Sense module. Designed for educational, environmental research, health monitoring, and prototyping applications this microscope features an OV2640 camera with a 10x magnification with precise motorized focusing, high-resolution imaging, and real-time TinyML processing for image handling. The microscope is modular and open-source making it easy to customize and expand its features using 3D-printed parts, motorized stages, and additional sensors. It supports Wi-Fi connectivity with a durable body, uses USB-C for power and swappable objectives make it usable in various applications.

Ricardo García ☛ Bespoke solution to monitor power outages at home
When I came home from a 5-days family trip this summer I immediately realized power was off in our flat. The main switch in the electricity panel was down together with one other additional switch. Everything appeared to have happened a few days before we arrived, so a few things in the fridge were ruined and most of the freezer contents had to be discarded. This was despite the fact we have relatives living close by with an emergency set of keys but, as we were completely unaware of the events, we couldn’t ask them to go check.
I thought about what happened and decided I wanted to set something up so I would get warned if power fails while I’m away. My first thoughts were using something that was available off-the-shelf, but I failed to find something cheap and easy. Fortunately, I already had a couple of things that could help me in this: a small cloud server (that hosts this blog) and a permanently-connected RPi4 that I use as a Pi-Hole at home. To be warned of a power failure, I wanted to use my RPi to ping (somehow) the clown server from time to time and, on the clown server, periodically check if we have received a recent ping. If too much time goes by without receiving a ping from home, we can assume something’s wrong and either we have a power outage or an Internet service outage.
